Muhammad 47:6

ذَٰلِكَ بِأَنَّ الَّذِينَ كَفَرُوا اتَّبَعُوا الْبَاطِلَ وَأَنَّ الَّذِينَ آمَنُوا اتَّبَعُوا الْحَقَّ مِن رَّبِّهِمْ ۚ كَذَٰلِكَ يَضْرِبُ اللَّهُ لِلنَّاسِ أَمْثَالَهُمْ

That is because those who disbelieve follow falsehood, and those who believe follow the truth from their Lord. Thus does Allah present to the people their comparisons.

فَإِذَا لَقِيتُمُ الَّذِينَ كَفَرُوا فَضَرْبَ الرِّقَابِ حَتَّىٰ إِذَا أَثْخَنتُمُوهُمْ فَشُدُّوا الْوَثَاقَ فَإِمَّا مَنًّا بَعْدُ وَإِمَّا فِدَاءً حَتَّىٰ تَضَعَ الْحَرْبُ أَوْزَارَهَا ۚ ذَٰلِكَ وَلَوْ يَشَاءُ اللَّهُ لَانتَصَرَ مِنْهُمْ وَلَـٰكِن لِّيَبْلُوَ بَعْضَكُم بِبَعْضٍ ۗ وَالَّذِينَ قُتِلُوا فِي سَبِيلِ اللَّهِ فَلَن يُضِلَّ أَعْمَالَهُمْ

So when you meet those who disbelieve [in battle], strike [their] necks until, when you have inflicted slaughter upon them, then secure their bonds, and either [confer] favor afterwards or ransom [them] until the war lays down its burdens. That [is the command]. And if Allah had willed, He could have taken vengeance upon them [Himself], but [He ordered armed struggle] to test some of you by means of others. And those who are killed in the cause of Allah - never will He waste their deeds.

سَيَهْدِيهِمْ وَيُصْلِحُ بَالَهُمْ

He will guide them and amend their condition

يَا أَيُّهَا الَّذِينَ آمَنُوا إِن تَنصُرُوا اللَّهَ يَنصُرْكُمْ وَيُثَبِّتْ أَقْدَامَكُمْ

O you who have believed, if you support Allah, He will support you and plant firmly your feet.

وَالَّذِينَ كَفَرُوا فَتَعْسًا لَّهُمْ وَأَضَلَّ أَعْمَالَهُمْ

But those who disbelieve - for them is misery, and He will waste their deeds.

ذَٰلِكَ بِأَنَّهُمْ كَرِهُوا مَا أَنزَلَ اللَّهُ فَأَحْبَطَ أَعْمَالَهُمْ

That is because they disliked what Allah revealed, so He rendered worthless their deeds.
